$\bf\Huge\red{\mid{\overline{\underline{ ANSWER }}}\mid }$

➡️Given 5 flags of different colours

➡️We know the signal requires 2 flags.

➡️The number of flags possible for upper flag is 5.

➡️Now as one of the flag is taken, the number of flags remaining for lower flag in the signal is 4.

➡️The number of ways in which signal can be given = 5 × 4 = 20.
